Primary Outcome Measures
NameTimeMethod
Percent Change From Baseline in Erosion Index (A Ratio of Curve-like Structures to Plate-like Structures and is a Measure of the Degree of Structural Degradation) of the Distal Radius12 months

The percent was change from baseline in erosion index at the distal radius between the risedronate and placebo groups at Month 12 (the lower the percent change in erosion index, the greater the improvement of structural degradation); the last valid postbaseline measurement was to be used when the Month 12 value was missing (Last Observation Carried Forward or LOCF).

NOTE: The study was unable to recruit sufficient numbers of patients to meet with the protocol specified numbers, thus it was terminated early after 5 months. No efficacy analyses were performed.

Secondary Outcome Measures
NameTimeMethod
Erosion Index of the Distal Radius6 months

Study was terminated prior to acquiring any efficacy endpoints. No efficacy analyses were performed.
